Inventor: ELMER STEFAN
IPC: B23D55/10
Filed: 1983-05-30
Abstract: A band saw wherein one of the pulleys for an endless band-like blade is movable toward and away from the other pulley to relax the tension upon or to tension the blade. The one pulley is permanently biased away from the other pulley by a relatively weak spring whose bias can be overcome by hand to facilitate the removal of a blade or the application of a fresh blade. In addition, the one pulley is normally biased away from the other pulley with a pronounced force by a package of dished springs whose bias upon the one pulley can be interrupted by a single-acting cylinder and piston unit whose piston is installed between the dished springs and a reciprocable carriage for the one pulley. The dished springs react against a support for the pulleys and bear against the piston. Two twisting units are provided to maintain a central portion of one of the two elongated reaches of the blade in a plane which is normal to the axes of the pulleys, and such twisting units can be pivoted or otherwise moved into and from engagement with the one reach by fluid-operated motors.

Patent DE-3337280-A1 (DE)
Title: Data protection device
Inventor: HOEGENER HANS-JUERGEN DIPL ING
IPC: G06F11/00
Filed: 1983-10-13
Abstract: The invention relates to a data protection device for protecting data in electronic circuits, particularly microprocessors, by detecting and early signalling of mains failure or mains undervoltage in the area of the power supply. The drop in the mains voltage is detected via an output A of the switched-mode power supply which is connected to a controlled system which represents a function of the input and output voltage. Signalling to the electronic circuit (2) is effected by a flip-flop (3) which is in series with a comparator circuit (4) and is driven by its output. For this purpose, the output (A) of the switched-mode power supply (1) is connected via a voltage divider to the non-inverting input of the comparator circuit (4) whilst the inverting input is connected to a reference point B which is set to the corresponding voltage level by a resistor (10) and a Zener diode (14). An undervoltage monitor (7) is used for detecting the operating range during the running-up of the supply voltage and switches the flip-flop back into its initial state. A battery (5) is used as additional time buffer and increases the safety of the circuit. <IMAGE>

Patent DE-3344320-A1 (DE)
Title: Universal card for a nuclear reactor protection system
Inventor: HILL WILLIAM DAVID
IPC: G06F11/22
Filed: 1983-12-08
Abstract: The card forms a channel in a self-test system for a nuclear reactor plant, which system supplements the nuclear reactor protection system, and is preprogrammed in digital logic so that it operates equivalently to an analog circuit during the actual plant operation. In the system-controlled monitoring, a central microprocessor (34) serially addresses circuit cards and loads test commands into these cards. The addressed cards are subsequently simultaneously activated by a system-wide command. A test pulse, which is transparent to the system due to its short duration and therefore does not activate the system, is passed through the actual programme-operated components by the preprogrammed channel logic on the universal card in order to check the functional capability of the system along the actual operating path. The initial state of the system is recorded in output registers (40, 42, 44) and then read under control of the controller computer memory (32). If no system-wide test is performed, the programmed card is monitored by a secondary loop computer which checks RAM and ROM memories and continuously monitors the system timers (26) and verifies the accuracy of the transfer function within the card in dependence on the total status. <IMAGE>

Title: Fuel injection nozzle for internal combustion engines
Inventor: TRACHTE DIETRICH DIPL ING
IPC: F02M45/08
Filed: 1983-12-08
Abstract: Fuel injection nozzle for internal combustion engines with a valve needle (12) which, at the end of a pre-injection lift, directly or indirectly opens a secondary duct (56), by way of which the fuel pressure is admitted for acting on an accumulator piston (34) and an exposed annular area (50) acting in the closing direction of the valve needle (12). As a result, the valve needle (12) is temporarily returned to the valve seat and the closing pressure is considerably increased. The ensuing main injection phase is initiated at a correspondingly higher fuel pressure and the higher closing pressure continues to act up to the end of the injection process, resulting in a precise closing of the valve needle. <IMAGE>

Title: Mounting for sensors
Inventor: ECHLE BERNHARD DIPL ING
IPC: G01K1/14
Filed: 1984-04-06
Abstract: The invention relates to a mounting for sensors for monitoring and controlling the sterilisation of open solutions in wide-necked vessels. When sterilising open solutions it is necessary, for monitoring and controlling the sterilisation process, to fit a vessel with a sensor which serves to determine the current sterilisation conditions. To this end, an accurately predefined position of the sensor relative to the wide-necked vessel, and in particular in the central axis thereof, has to be reliably maintained during the entire sterilisation process. According to the invention, accurate mounting of the sensor is achieved by the mounting having at least three supports which project radially outward from a centre of a central part and which can be laid onto the vessel opening rim, and by at least one slidable end stop being mounted on each support, and by the mounting having a continuous cut-out, which is disposed coaxial to the centre and is adjustable, by means of the end stops, coaxially with respect to the central axis of the vessel, within which continuous cut-out the elongated sensor can be moved and retained. <IMAGE>
